How to activate CloudFlare

This article describes how to activate CloudFlare for your web site.

Activating CloudFlare

There are two ways to activate CloudFlare for an account:

  • Use the CloudFlare cPanel plugin.
  • Sign up on CloudFlare's web site directly.

When you activate CloudFlare using the cPanel plugin, A2 Hosting manages your web site's DNS settings. You can quickly and easily enable and disable CloudFlare for your domain and subdomains from within cPanel, as well as view basic site statistics.

When you activate CloudFlare directly from their web site, CloudFlare manages your web site's DNS settings, and you use the CloudFlare site to manage settings for your domains. You cannot use the cPanel plugin to manage CloudFlare.

Which activation method you use depends on how you want to manage your CloudFlare and DNS settings (that is, from within cPanel or by logging into a separate site). Of course, if your account does not include cPanel, then you must activate CloudFlare using their web site.

Method #1: Activating CloudFlare from cPanel

To activate CloudFlare for your web site using the cPanel plugin, follow these steps:

  1. Log in to cPanel.
    If you do not know how to log in to your cPanel account, please see this article.
  2. In the Software/Services section of the cPanel home screen, click CloudFlare.
  3. In the Your Email text box, type your e-mail address.
  4. Select the Terms of Service check box, and then click Signup Now!.
  5. On the Activate CloudFlare page under CloudFlare Status, click the gray cloud (CloudFlare - gray cloud icon) icon next to the root domain you want to enable.
  6. When CloudFlare activation is complete, the cloud icon turns orange (CloudFlare - orange cloud icon). You can now configure CloudFlare for your account.
    When you try to activate CloudFlare in cPanel, you may receive the following error message:
    Error Refresh the page and try again.
    Error response: We have detected that you are attempting to add a subdomain, or a zone that is already active on CloudFlare under a different account.

    This problem occurs if you previously set up CloudFlare for your domain using CloudFlare's own web site (instead of cPanel). To resolve this issue, log in to your existing account on the CloudFlare web site, and then delete the site. After you delete the site, you can use cPanel to activate CloudFlare for the domain.

Method #2: Activating CloudFlare directly from their web site

To activate CloudFlare directly from their web site, follow these steps:

  1. Use your web browser to go to
  2. Click Sign up.
  3. Follow the on-screen prompts and provide the requested information.
  4. After your account is activated, manage settings by logging into the CloudFlare web site.
    When you activate CloudFlare directly from their web site, you cannot use the cPanel plugin to manage settings for your account. Use the CloudFlare site instead to manage all CloudFlare settings for your account. For information about how to do this, please visit
